Specification of Letters Patent. PmIj mt fi Aug, 31 19115,

Application filed November 9, 1911. Serial No. 659,284.

To aZZ whom it may concern:

Beitknown that I, JOHN R. Rooms, a citizen of the United States, and a resident of Brooklyn, county of Kings, and State of New York, have invented a new and useful Im rovement in Line-Casting Machines, of which the following is a specification.

This invention has reference to thatclass of linotype machines in which a series of superposed magazines is mounted on a frame movable upward and downward under the influence of a central upright screw, as shown in Letters Patent of the United States No. 859,618, granted to me J an. 19th, 1906. In the construction shown in the patent the operator is required to pass behind the machine and operate a hand crank to eifect the raising and lowering of the magazines. The present invention has reference to power driven means for this purpose controllable by the operator while seated at the keyboard ofthe machine; so

that the adjustment of the magazines, and

the change from one style of type face to another, may be efiected instantly and easily, and without material interruption of the composing operation.

In the drawings I have represented only' those parts of the machine which are necessary to an understanding of my invention; and it is to be understood that in all other respects the machine may be of the construction shown in the said patent or of the construction shown in my Letters Patent No. 1,109,872, dated September 8th, 1914.

In the drawings: Figure 1 is a perspective view showing the upper portion of the main frame, the magazines, and their sup porting and operating mechanisms. Fig. 2 is a horizontal cross-section through the mechanism' for operating the screw.

Referring to the drawings, A represents the main frame of the machine, B the inclined, superposed magazines in which the matrices are carried, C the base frame underlying and sustaining the magazines, D a central shaft or .post sustaining the base frame, E a sleeve secured rigidly to the' main frame, serving to support and guide the post D. Also located in the sleeve is the screw F,..which when actuated raises or lowers the post and base frame so as to bring one magazine or another to the operative level.

G is a beveled gear secured to the lower end of the screw F and H is a beveled pinion mounted in a bearing in the fixed sleeve gear G for the purpose opposite end the relatively larger gear wheel K.

L and L are two beveled pinions in permanent engagement with the gear K, on opposite sides of its center. The pinions L and L are secured respectively to hubs Z and Z, mounted to turn loosely on the horizontal and constantly driven shaft M, forming part of the 'linotype machine of commerce and commonly known in the art as the intermediate shaft, and which operates the assembling and distributing devices.- N is a sleeve with conical ends mounted on the shaft M between the hubs Z and Z. This sleeve is connected with the shaft by a spline Z so that it may slide endwise, and the ends are made of conical form to enter corresponding cavities in the inner ends of the hubs Z and Z, the combination of parts forming two friction clutches.

The sleeve N is constantly rotated. If moved to the left it will engage the hub Z and rotatethe pinion L, thereby communicating' motion, through gear K and the inframe by a vertical pivot n".

to the right or left the magazines may be caused to rise or fall to any required extent. l/Vhen the lever is released and left in the central position, both the clutches will be disconnected and the magazines will remain at rest.

In machines of this class it is customary to lock the magazines rigidly in the position to which they are adjusted by means of a bar 0, mounted to slide endwise in the main frame and enter the notches 0, at different heights in'the bars attached to the baseframe that carries 'the magazines. When the locking bar 0 is moved forward the magazine will be released. When any ,magazine reaches the operative level the notches 0 will stand in line with the lockingbar 0, which will be automatically moved endwise to enter the notches by a spring 0'. In order that the machine may operate properly it is necessary that this locking bar shall be disconnected before the magazlnes are shifted. For this purpose I pivot to the clutch controlling lever 11. a second lever P, connected by a link p, to an upright lever 29, pivoted at p to the lever 11?. The upper end of the lever p acts on a sliding pm p guided in the main frame and acting on an elbow lever 12, also pivoted to the frame. The lever 79* acts in turn on a connecting rod 12 pivoted at its upper end to an angular lever p.- This lever is pivoted at p to the main frame, and has its upper end slotted to engage the pin p in the locking-bar 0.

When the movement of the magazines is to be efiected the operator grasps the levers P and n in one hand and first moves the le ver P toward its companion, the effect being to .move the locking-bar O and release the magazines. After this is done the lever n is moved to the left or right according to the direction in which the magazines are to be moved. During the movement of the magazines the lever P is released, so that when the selected magazine reaches the o'perative level the spring 0' may pull the locking-bar into engagement. The instant this occurs the lever n is released and the movement of the magazines ceases.

Having described my invention, what I claim is: v

1. In a typographical machine, the combination with a plurality of magazines, a supporting frame therefor, and a screw attached to the supporting frame and wholly sustaining the same, of means for rotating the screw to raise or lower the magazines to bring one or another into operative posi-.

tion, the said means comprising the constantly driven intermediate shaft, and means deriving motion from said shaft for rotating the screw in one direction or the other as required.

By simply moving the forward end of this hand-lever 2. In a typographical machine, the combination with a plurality of magazines, a supporting frame therefor, and a screw attached to the supporting frame and wholly sustaining the same, of means for rotating the screw to raise or lower the magazines to bring one or another into operative position, the said means comprising the constantly driven intermediate shaft M, the connecting shaft I geared to the screw, and a reversible gear and friction clutch whereby the two shafts are operatively connected when desired.

3. In a typographical machine, the combination of a plurality of movable magazines, reversible powerdriven mechanism for raising and lowering them comprising a shiftable clutch member, means for looking the magazines in operative position, and manually-operable devices controlling both the said clutch member and locking means.

4. In a typographical machine, the combination of a plurality of, movable magazines, a screw to raise and lower them, reversible power-driven mechanism for actuating the screw. comprising a shiftable clutch member, means for locking the magazines in their adjusted positions, and manually-operable devices serving to control both said clutch member and the locking means.

5. In a typographical machine, the combination witha plurality of magazines, a supporting frame therefor, and a screw attached to the supporting frame and wholly sustaining the same, of means for rotating the screw to raise or lower the magazines to bring one or another into operative position, the said means comprising the constantly driven intermediate shaft M, the

connecting shaft I geared to the screw, the reversible gear and friction clutch to connect the two shafts, and a hand lever arranged. adjacent to the keyboard for operating the friction clutch.

6. In a typographical machine, the combination of a plurality of movable magazines, the magazine-elevating screw F, the constantly driven clutch member N, reversible connections between said member and the screw, a hand lever connected with the clutch member, means for locking the magazines in their adjusted positions, a secondlever mounted on said hand lever, and connections from said second lever to the locking means.

7. In a typographical machine, the combination of a movable magazine, reversible power-driven mechanism to shift it into operative relation to the other parts comprising a shiftable clutch member,locking means to engage the magazine in its shifted position, and connected controlling devices for Y the clutch member and the locking means.
